Cosmogenic nuclide dating definition
The only way to avoid making such assumptions and simultaneously determining both the erosion rate and the exposure age is to measure two nuclides with different half lives. This is the so-called zero erosion line, which groups all samples that can be used for proper exposure dating. The most important example of studies which require samples that plot on the zero erosion line are exposure dating studies of glacial retreat.
Cosmogenic nuclides such as 10Be accumulate in the first 2m or so below the cosmogenic nuclide dating definition. These rocks are removed and transported down the drainage network, carrying the cosmogenic nuclide signal with them. Obviously, the most common application of burial dating is the dating of cave sediments.
To apply the cosmogenic nuclide method to other field settings, the production rates must be scaled to a common reference at sea level and high latitude SLHL.
